Dkamtryn Decamethrine
The chemical structure of this compound contains bromine (Br), which is almost insoluble in water and is soluble in water only to the extent of 0.002 ppm. However, acetone, and is soluble in many solvents ring. Artificial Pyrvtrvyydhay very unstable part of lepidopteran larvae and Some Beetles are effective. High insecticidal power and about 50 times for the oldest I housefly toxic.
Pesticides property of the toxin by Elliott discovered by Shell in 1975 and has been marketed. Molecular formula: C22H19cl2No5 been. In its pure form is a solid substance with a melting point of 8060 degrees Celsius. Almost insoluble in water but is soluble in organic countertrade solvents as well. Neutral and acidic environments are weak, good stability, countertrade but is decomposed in alkaline environments. Relatively resistant against light and small breaks. The large number of insects, particularly lepidopteran larvae is effective.
These compounds have insecticidal properties and is Knhkshy. In 1981 the company manufactured and marketed by Sumitomo of Japan. 50 to 200 g N ha is effective on insects and ticks types. This combination is extremely dangerous to humans and animals. 14070 = LD50 mg per kg body weight for rats. This combined with alkaline compounds that should not be mixed. This Knhksh emulsion of 10% against European red mite is recommended. But Aryvfyd not effective on ticks. Read the rest ...
Be mixed with other fungicides and insecticides is. Oral LD50 for rats 16,001,400 (Rsmtryn) and 88008600 (Byvrsmtryn) and percutaneous respectively 4200 and 10000 mg kg body weight. Bayesian surface countertrade of the disk 250 mg per kg of body weight countertrade for three months has been fed. Does not cause skin sensitization. As with other pyrethroid is toxic to fish.
Dltn its molecular weight 331.42 Molecular Formula C1H25NO4, the toxin by Sumitomo companies, Fyrflyd created and first introduced in 1965. In its pure form as colorless crystals, melting point 8060 C (technical 90%) Boiling point 190 185 C, 0.13 mbar, 20 C Vapor Pressure: 810 * 4.7 mm at the time. Sensitive towards acids and strong countertrade bases. The storage temperature up to 50 C is stable. countertrade Practically insoluble in water, but in 40% acetone, benzene, 50% toluene and 40% is resolved well. Effect of contact and a good blow.
Of the toxin to fight the flies, mosquitoes, bees, used in homes and farms. Pyprvnyl Bvtvksayd also be used mixed aerosol. Market in liquid form in pressurized canisters, killing 50% of the emulsion through the digestive rat 5200 mg per kg of body weight. Feeding dogs 12502500 and 5000 mg per kg of body weight countertrade in 13 weeks without any complications and symptoms of poisoning after feeding countertrade has not been established. It is toxic to fish. Tolerance countertrade limit for fish CTS is 0.18 mg per liter in 48 hours and also is toxic to bees.
Molecular formula C21H28O3 (variable), molecular weight: countertrade 328.43 (Dltn) toxin by factories Dnka, Fyrfyld, made and marketed. In its pure form is a thick oil. The boiling point of 170 200 C, the vapor pressure is very low. The environment is very unstable, so in the presence of light and air oxidizes and loses its insecticidal properties. It is also ineffective in alkaline environments. Add to establishing synergistic properties. countertrade Practically insoluble in water but is soluble in organic solvents as well. It is a contact poison effect. It is insecticidal to combat insects and warehouses used in the home and in public places. Also to combat aphids, scale insects and other pests in vegetables and vegetable gardens, and storage pests is recommended. Following Prvnyl Bvtvksayd countertrade it is synergistic. Rvtnvn usually mixed with other insecticides used.
Overall, with the exception of alkaline compounds with good compatibility. Lethal level of 50 percent countertrade between 570 to 1500 mg orally in rats kg range. Rapidly hydrolyzed in the body and it loses its effectiveness. Contact toxicity is measured. Acceptable concentration at work in 8 hours, 15 mg per cubic meter of air volume. Is toxic to fish. The emulsion is toxic to bees. The spray is not toxic to bees away is. When a mammal is warm blooded animals decomposed by hydrolysis of the ester chain is done. Breakdown by sunlight and ultraviolet radiation in the alcohol group began and led to a number of derivatives is unknown.
Molecular formula C23H24O4S, molecular weight: 396.5 is Dltn. This toxin is manufactured countertrade by Russell Avklaf and supply markets. In its pure form as a yellow oil emulsion and thick terracotta, 710 x 6.5 mm vapor pressure at 20 C under load. Alkaline hydrolysis in liquid environments and the light will break.
Oral LD50 for rats 3200 1421324 and Percutaneous kg body weight. Skin, eyes and respiratory countertrade tract can cause some sensitivity. Bayesian level to male rats for 30 days at 1.25 mg per kg of body weight was measured. Fish
